On Tuesday, Verizon Wireless announced that HD Voice and Video Calling would be coming to the company's 4G LTE network. In coming weeks, Verizon customers with smartphones capable of these features will finally be able to take advantage of them.

Better known as VoLTE (Voice Over LTE), this new service allows for better quality, high definition sound in voice calls using the 4G LTE network instead of forcing the device you're calling from to drop down to a 3G network for calling and impacting sound quality.

Not all devices support VoLTE, and if you have a VoLTE smartphone and the person you're calling doesn't, then you're still going to be stuck with a regular-quality phone call; this also applies if you're calling someone on another carrier. The feature kicks in when both phone users have a VoLTE smartphone and are using the Verizon Wireless 4G LTE network in range of the feature.

Because the feature is an emerging feature, we expect that the restrictions will be lifted in the future as it becomes more widespread among different carriers and smartphones. The upcoming iPhone 6, which Apple is expected to unveil some time this Fall, may or may not support VoLTE.
